You can automatically purge the backing pump for 20 seconds when you change to
"Standby".

If you switch off the automatic purging, you can switch purging on or off in the
standby window by pressing .

Regeneration It may happen that too much helium has entered the interior of the device and no
accurate measurements are possible (helium contamination). The regeneration
provides the user with an automatic start-stop-vent cycle to degrade such elevated
helium background.
An active regeneration is shown in the display.
Regeneration is automatically deactivated after 60 minutes.

ð
You can start the regeneration in the opened window and stop it as desired or
wait for the automatic deactivation of the regeneration after 60 minutes.
6.3.13 Change leak rate filter
The leak rate filter “I•CAL” is preset. I•CAL ensures that the averaging time is optimally
adapted to the leak rate range.
The abbreviation I•CAL stands for “Intelligent Calculation Algorithm for leak rates”.
This ensures that the signals are averaged at optimal time intervals and this is based
on each leak rate range. I•CAL also determines interference spikes, which bear no
relevance to the leak rate signals and delivers unusually short reaction times even
with low leak rate signals. The algorithm used offers excellent sensitivity and response
time.
With the leak rate filter "Fixed" there is also a filter with a fixed time constant available.
Procedure ü Supervisor rights
1 > Setup > Measurement > ZERO and filter
2 Make a selection between “I•CAL“ and “Fixed” under “Leakage rate filter”.
